Abstract

A perimeter monitoring device for a work vehicle is configured to monitor a surrounding of the work vehicle and display a monitored result on a display device. The perimeter monitoring device includes cameras, a bird's-eye image display unit, obstacle detecting sensors, a camera image specifying unit, and a camera image displaying unit. The camera image specifying unit is configured to specify one or more camera images in which one or more of obstacles are captured when the one or more of obstacles are detected by the obstacle detecting sensors. The camera image displaying unit is configured to display a relevant camera image in alignment with the bird's-eye image on the display device when a plurality of camera images are specified by the camera image specifying unit, the relevant camera image being ranked in a high priority ranking based on a priority order set in accordance with travelling states.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority to Japanese Patent Application No. 2011-127476 filed on Jun. 7, 2011, and Japanese Patent Application No. 2011-129461 filed on Jun. 9, 2011, the disclosures of which are hereby incorporated herein by reference in their entireties.TECHNICAL FIELD[0002]The present invention relates to a perimeter monitoring device, and particularly to a perimeter monitoring device configured to monitor the surrounding of a work vehicle and display a monitored result on a display device.BACKGROUND ART[0003]Dump trucks, used for carrying crushed stones in mines or etc., have been provided as supersized work vehicles. Compared to vehicles such as normal trucks, dump trucks of this type have a remarkably large vehicle width and a large longitudinal length. Therefore, it is difficult for operators thereof to grasp surrounding statuses by means of side mirrors and etc. In view of this, as described in U.S. Patent Application Publi...
